Turnover calculation query

The assistance from the community was great and I have been exploring Domo. This request is in continuation with this data set https://dojo.domo.com/discussion/comment/55564#Comment_55564

Based on the turnover calculation in the excel file, I would like to get some guidance on whether it can be done on the beast mode or does it require another ETL process. I would really appreciate how I could incorporate these excel formulas into Domo for every month's turnover calculation to display the using the 24 months data. Thanks in advance.
